Airpipe simplifies terminal P2P file transfers

Airpipe strikes an excellent balance between the convenience of web-based file sharing and the security of CLI tools. Its zero-knowledge architecture and seamless fallback relay make it a highly practical addition to any developer's toolkit.

• –**Zero-Knowledge Architecture:** Client-side NaCl secretbox encryption (XSalsa20-Poly1305) ensures the relay server never accesses file contents or keys.
• –**Flexible Transfer Modes:** Leverages direct WebRTC P2P streaming when both sides are online, with an automatic 10-minute encrypted mailbox fallback when asynchronous.
• –**Frictionless Pairing:** Operates identically across terminal sessions and browser instances using a temporary generated passphrase or QR code, requiring no accounts or complex configuration.
• –**Lightweight Self-Hosting:** The Go-based relay can be deployed via a single 15MB Docker container, allowing teams to quickly establish private file sharing infrastructure.
